TOY AEROPLANE,

Application led November 1921,. Serial No. 517,815.

To all whom t concern." j

Be it known that l, PERCY PIERCE, acitizen of the United States, and a residentA of Philadelphia, county of Philadelphia, State .of Pennsylvania, have invented certain new and usefulA Improvements in Toy Aeroplanes, vof which the following is a specification.v f

Some of the objects of the present in vention are to provide an'improved aerial toy arranged to iy in simulation of an aeroplane; to provide a blank of suitable material arranged to'be folded in sucha way as to produce a completevaeroplane*which when thrown will Hy in realistic manner to ,provide a'one piece blank so shaped and arranged as to be readily folded into aero plane form; to provide an improved folded toy aeroplane having .means to sustain and stabilize the aeroplaneV inight; to provide means for reinforcing the sustaining Wings vof a toy aeroplane; and to provide other improvements as will hereinafter appear.

ln the accompanying drawings, Fig.v 1 represents a plan of a blank for forming a toy aeroplane embodying one form ofy the present invention; Fig. 2 represents a plan of the aeroplane showing one step in its construction; Fig. 3 represents a plan of the completed aeroplane as formed by "folding the blank of Fig. 1; Fig. 4 is a side eleva.- tion of the completed aeroplane; Fig. 5 is a front elevation of the same; Fig. G represents a plan ofa blank for forming a toy aeroplane embodying another form of the present invention; Fig. 7 represents a perspective of a detail of construction employed with the aeroplane of Fig.v 6; and Fig. 8 represents a perspective of the coinpleted aeroplane, formed from the blank of Fig. 6, in launching position.

Referring to Figs. 1 to 5 of the drawings one form of a toy aeroplane embodying the present invention is shown comprising a blank 1() cut from any suitable material. such as a relatively stiff paper or any other readily shaped sheet.

For the purpose of forming the fuselage of the aeroplane, the blank 10 has an elongated, longitudinally disposed body 11 having a rearwardly tapered portion 12 which terminates in an outwardly iared tailpiece 13, the extremity of which is provided with two oppositely arranged lateral projections y the body.

the aeroplane, the. body llhas two wingsl extending in opposite ,directions and in aligned relation, and forming a slight dihedral angle, while their respective-front edges are' in the same straight line passing at right angles to the longitudinal axisv of 0 As a 4means for-stabilizing the aeroplane 1n flight, the tail piece 13is`providedwith oppositelydisposed laterally projecting ele vating wings 16 which are"relative ly small as compared tothe sustainingwfings 15. The respective outer'edges 17 ofthe wings 16 curveoutwardly and i'earwardlyso that the surface exposedto the air gradually increases inv area toward the tailv of the aeroplane.` y A If it is desired to provide a figuresimulating an aviator, the blank 10 is provided at'tl'ie front of the body v11 with an extenvsion support 20 having flap members 21 formed thereon for the purpose of simulating a human tigureby printing thereon'or otherwise.

For the purpose of protecting the front edge of the'respective sustaining Wings 15 andalso maintaining them in correct position for proper flying,'a strip 22 is provided, .preferably of thin metal, to give the necessary rigidity but of sufiicient 'duetilityto be readily bent to` the desired shape. This strip 22, when foldedleng'thwise, is fitted lover the front Wing edges from tip to tip and pressed sothat it is firmly clamped `to the blank material, thereby forininga rigid reinforcement which prevents damage to the wings 15 in Hight. Also this reinforcement strip 22seadies the aeroplane and counter-` acts the effect of air currents tending to disturb the balance. While it is preferable to employ a metal strip 22,'it will be understood that any other suitable material giving the desired result may be employed. The blank 10 with its attached strip 22 is shown inv Fig. 2, with the aviator support 20 foldedI back to position, ready for the complete folding operations.

To form the aeroplane the blank 10 is first folded along the medial line, indicated -dotted at 23 in Fig. 2, after which one wing 15 is folded outward along dotted line 24, and the other Wing 15 is folded outward along dotted line 25. Those operations provide the substantially vertical fusela e body 11 having vertical rudders 26 and tile substantially horizontal side Wings 15, the area of which is such as to sustainthe body in the air when propelled with sufficient force. The stabilizing wings 16 are now formed by folding the tail portion 13 along the .re,

Spective dotted lines 27 and 28 to give a forward pitch to the upper surface of the wings 16. As seen in Figs. 4 and 5, the construction is such that the inclined wings 16 are to the rear of the wings 15 and below them, and consequently they are exposed to the current of air passing rearwardly under thewirgs 15 and function to hold the tail piece 13 down so that the aeroplane is maintained in flying position insteadof making a nose dive as soon as thrown. It will be noted also that the stabilizing effect is 'insured by proportioning the area of the wings 16 with respect to the weight of the strip 22 to give the desired equilibrium.

In Figs.. 6 and 7 another form of blank 30 is shown for use with a reinforcing strip 31 of cardboard or like stifening material.A

In this formvtheblank 30fis provided with flaps 32 formed on the front edge and arpasted against the opposite` side. This not only holds the folded portions firmly loutl gives a reinforcement to the part held in .throwing the device. To further strengthen the position of the body where it is held for throwing, and also to reinforce the bent portion of the strip 31, there is an auxiliary strip 38 pasted across from one wing 40 to the other wing 41 before the flaps 32 are pasted down in place.

From the foregoin it will be apparent that in either form o the invention a complete flying toy is provided wherein stability With sustaining power causes the aeroplane to fly smoothly in a given direction, without the usual darting or diving motions common to toys of this character. Any tend ency of the aeroplane to fall into a nose dive is compensated for by the arrangement of the small elevating wings 16 on the tail because the applied force of the air acts against their top surface in opposition' to the gravity pull of the reinforcement strip 22. These wings 16, like the sustaining wings 15, project laterally from the body 12 and form a slight dihedral angle with each other in the same manner as do the wings 15, so that the entire structure functions to prevent improper tilting about either a horizontal or a vertical axis.

Attention Yis also directed to the simplicity of construction in thaty a onev piece blank serves to form the aeroplane body, the wings, the stabilizing means and the tail, .the whole being stamped or cut out at one operation ready forthe folding operations. It will be noted that the strip 22 preferably extends the full length of the front edge of the wings 15, thereby giving the` required rigidity of construction and balance to the parts.

Havingthus` described my invention, I claim: f

In a toy, a one piece blank folded to form an aeroplane having a fuselage,sus taining wings, elevating wings and a tail rudder, in combination with a strip-of reinforcing material superimposed upon the front edge of said sustaining wings and extending the full length thereof.
